| Description | Scapolite is the name of a series between the sodium chloride rich mineral called marialite and the calcium carbonate rich mineral meionite. Scapolite forms in metamorphic rocks from the alteration of plagioclase feldspars. Scapolite is commonly found in stubby to long prismatic crystals. It belongs to the exclusive symmetry class called the Tetragonal Dipyramidal Class. It has the chemical formula Na4(Al,Si)12O24Cl to Ca4(Al,Si)12O24(CO3,SO4). The name comes from the Greek, skapos, meaning rod and, lithos, meaning stone. |
